What is a pressure ulcer?

A pressure ulcer, also known as a bedsore or decubitus ulcer, is a sore that develops on the skin as a result of prolonged pressure. This condition typically arises in individuals who are immobile or have limited mobility, as continuous pressure on specific areas of the skin reduces blood flow, leading to tissue damage and skin breakdown.

Understanding pressure ulcers is crucial for nursing assistants, as they play a vital role in preventing these injuries through proper patient positioning, regular skin assessments, and implementing turning schedules for those who are unable to move independently. Recognizing the signs and symptoms early on can lead to effective management and better patient outcomes. In contrast, the other options do not accurately describe what a pressure ulcer is, which is specifically linked to pressure rather than infections, dryness, or allergic reactions.
